Orbit and dynamics

Between its closest point (1.004 AU) and its farthest (3.418 AU), the heliocentric distance changes by 2.414 AU over every revolution.

One full revolution takes 3.29 yr (1,201 days), computed from the semi-major axis of 2.211 AU.

The high eccentricity (0.546) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.

A steep inclination of 23.77° carries it well above and below the ecliptic plane.

By the vis-viva equation its orbital speed rises to 37 km/s at perihelion and falls to 10.9 km/s at aphelion.

Size and surface

No direct size measurement is available; from an absolute magnitude of H = 14.71 and an assumed geometric albedo of 0.14, the diameter works out to roughly 4.06 km.

Observation record and orbit quality

Astrometry from 3,588 individual observations underpins this orbit; the fit leaves an RMS residual of 0.4354 arcseconds.

Condition code U = 0 means the orbit is very well determined, leaving only a small uncertainty in the future ephemeris.

About these computed values

Orbital periods, perihelion and aphelion speeds, and diameter estimates on this page are computed by SpaceAtlas from the JPL SBDB orbital elements. They are derived quantities, not values copied from the source catalogue.
